I bought a few, sounds like a good idea, not having to twist the barrel to advance the refill and flip the pen end for end. Was a little rough in the beginning with the clicker, but got smoother as you clicked it a few times. The 1st one I turned as suggested according to the photos but will change the profile on next one. I got 5 of them, i should have bought a few more for the price, they went up already. Carl
